Awesome job BC Fasteners! Arrived on time and undamaged. Fence posts today, tomorrow the world!

This tool saved me 60-90 minutes of hand work per mortise. The chain mortiser is expensive, but the productivity is enormous. I cut and cleaned 28 2x6" (4.5" deep) mortises in 4.5 hours (not including layout). Easy to use, accurate, repeatable. Two recommendations, clear the shavings immediately. Also, mark the base with a pen to ID the inside of the chain cutter for quick resets when returning to the original mortise wall. Final comment, the mortiser will work best for production work if the beams are square planed ahead of time.

Expensive but not as expensive as getting someone to do the job. Worked very well and made a sometimes tough job really easy. Look after it and it will hold its value for resale.

I'm building a timber frame barn and was contemplating cutting all of the joinery by hand (I have a lot of very good quality framing chisels, Japanese saws, etc. ), but the sheer number of large and deep mortises convinced me to spend the money on a chain mortiser. Oh. My. God. This machine is one of the best machines, woodworking or otherwise, that I have ever used. It easily and smoothly plunges a first mortise (about 11/16" x 2-1/16" with the 18mm chain) all the way through a 6x6. It has a depth setting which brings up the only negative... in a blind mortise the bottom will be rounded - you have to cut down about 1.25" deeper than your tenon. Then you rotate the chain to position 1 and cut again, then position 2 and cut a third time. You now have a mortise about 5" wide all the way through. Pull a lever and the chain moves forward about a half inch and the process repeats. If necessary, adjust the unit for the next cut and repeat. In my case, I'm cutting 2" x 5.5" all the way through... takes about 10 minutes per mortise and the result is a perfectly sized rectangular hole. It also will cut lap joints (for the tenon), but this is more difficult to set up. Can't recommend this tool enough. I planned to sell this machine when I'm done with the barn, but I might have to keep it just because it is so well engineered. Anyone want to buy some chisels?
